Fast transition from PCH to DCH for UMTS

摘要

Systems and methods for logically transitioning a client device or user equipment (UE) directly to a DCH state for the data path when an application layer application initiates an operation that may result in the transmission of large amounts of data, are presented. Upon detection of a condition that would warrant allocation of a dedicated channel, the UE may set the Traffic Volume Indicator in a subsequent cell update message to the network node. The node may then assign a dedicated channel and the UE may be transitioned to the dedicated channel state without a portion of the application data being first transmitted on a forward access channel or random access channel in a CELL_FACH state.

1. A method for transmitting data in a UMTS network, comprising:
receiving at a processor on a transceiver in a paging channel state, a request to transmit data on the network; determining, based on an anticipated size for the data, whether the data is to be transmitted via a dedicated channel; if the data is to be transmitted via a dedicated channel:
outputting on the network a message indicating a dedicated channel should be allocated for the transceiver; andconnecting the transceiver to a network node via a dedicated channel.
